  • Make architectural decisions with scalability, reliability, and maintainability in mind.
  • Collaborate closely with product and leadership on roadmap and execution.
  • Debug production issues and continuously improve system performance and reliability.

  • Proven experience building and operating SaaS platforms.
  • Solid production experience with Python.

  • Demonstrated experience using AI coding agents (e.g., Cursor, Windsurf, Claude).
  • Experience deploying and operating systems on AWS, GCP, or Azure.
  • Strong understanding of system design, APIs, and distributed systems.
  • Comfortable operating with ambiguity and high ownership in an early-stage startup.
  • Ability to work regularly from Irvine, CA (Orange County).
  • Experience scaling early-stage or recently funded products.
  • Familiarity with vector databases, embeddings, and RAG architectures.
  • Experience with security, authentication, and multi-tenant SaaS systems.
  • Prior founding or early startup experience.
  • Be a founding engineer with real ownership and influence.
